I should add, my AB (Adventurebilt Deluxe) Alden boots came back from the factory, and it looks to have been a manufacturing error. All is good with them now, they've been replaced with a properly sized tongue!
Marc Kitter who runs Adventurebilt Deluxe, is an authorized Alden dealer, but his boot that he sells is as per his own and Alden's specs to re-create the boot from late 70's early 80's as it would have appeared in Raiders. It has the darker brown leather, a heavier leather, darker welt, darker moc toe stitching and other construction pieces not found on today's standard 403, 404, and 405. Marc's are the 405 model with the old updates. This latest run also has the full leather lining on the inside (which I prefer to the cotton duck or previous 405's from Marc and previous standard 405). He can only do a custom run of 12. He usually starts up a new order of 12 once the latest order is completely fulfilled. I would email them from their site;
http://www.adventurebiltdeluxe.com and ask the status of a new order, or if they will do a new order. They are worth the money for sure.
Best person to advise would be Stefan or Marc at Adventurebilt Deluxe.
Also, the 403 is the code for the Indy boot with Brown Chromoexcel leather, and the 405 is the standard Indy in the waxhide brown leather (its also a lighter colour). Other then the leather type and colour, nothing is different. You can't go wrong with either 403 or 405. They are great boots! I have a pair of the standard 405 which are now about 2-3 years old, and they are still great!
